Why is there something rather than nothing? And what does ‘nothing’ really mean? More than a philosophical musing, understanding nothing may be the key to unlocking deep mysteries of the universe, from dark energy to why particles have mass. Journalist John Hockenberry hosts Nobel laureate Frank Wilczek, esteemed cosmologist John Barrow, and leading physicists Paul Davies and George Ellis as they explore physics, philosophy and the nothing they share.

When no one is looking, a particle has near limitless potential: it can be nearly anywhere. But measure it, and the particle snaps to one position. How do subatomic objects shed their quantum weirdness? Experts in the field of physics, including David Z. Albert, Sean Carroll, Sheldon Goldstein, Ruediger Schack, and moderator Brian Greene, discuss the history of quantum mechanics, current theories in the field, and possibilities for the future.

Forget what you think you know about dark matter. After a 30-year search for a single, as yet unidentified, species of dark matter particle that would make up some 25% of the mass of the universe, physicists are starting to consider novel explanations. Some envision invisible matter hiding within the folds of extra spatial dimensions. Others suggest not one kind of dark matter particle, but numerous species inhabiting a shadow universe. Others still conjecture that dark matter doesn’t exist, and instead propose that the laws of gravity need modification. We’ll bring together leading thinkers on dark matter—the revolutionary and conventional alike—for a distinctly unconventional discussion on the dark universe.

In recent years, machines have grown increasingly capable of listening, communicating, and learning—transforming the way they collaborate with us, and significantly impacting our economy, health, and daily routines. Who, or what, are these thinking machines? As we teach them to become more sophisticated, how will they complement our lives? What will separate their ways of thinking from ours? And what happens when these machines understand data, concepts, and behaviors too big or impenetrable for humans to grasp? We were joined by IBM’s WATSON, the computer Jeopardy! champion, along with leading roboticists and computer scientists, to explore the thinking machines of today and the possibilities to come in the not-too-distant future.

This is one of several films made at Imperial College London in conjunction with ICI. The entire film, except for a short end sequence, was shot in the laboratory of Professor Eric Laithwaite at Imperial College London. This is one of many examples demonstrating electromagnetic forces and in particular the linear induction motor for which Eric Laithwaite was famous. Many of what he called his 'toys' are seen, these are models that help demonstrate the concepts and forces of electromagnetic induction etc.
This was currently the best transfer from 16mm film that we had of this unique engineer in his 'work place', but for a better quality version please now go here: https://youtu.be/CmKF72CPR0s

Recently, Lola Eniola-Adefeso and colleagues published a commentary in Cell describing the systemic inequities in research funding through the NIH, which have created a barrier to the success of Black scientists. By funding applications from Black investigators at approximately half the rate of similarly trained white investigators, the NIH has created a burden on Black scientists that leads some to abandon academia, and slows or blocks promotion of others, limiting their scientific achievement and career trajectory.
In this webinar, Eniola-Adefeso shares her personal journey through academia and the set of recommendations offered in the article for NIH policies to eliminate the funding disparity, as well as action items for fellow scientists, the private sector, and academia to overcome the racism that is endemic in the sciences.
0:01 Introduction by Pat Stayton
7:08 Lola Eniola-Adefeso Begins Presentation
1:15:50 Q&A
This event was moderated by Pat Stayton, PhD, Director, Molecular Engineering and Sciences Institute, University of Washington
About the Speaker:
Lola Eniola-Adefeso is the University Diversity and Social Transformation Professor in the Department of Chemical Engineering at the University of Michigan, as well as a Miller Scholar and Vice Chair for Graduate Studies at the University of Michigan. She is also the co-founder of Asalyxa Bio, which is developing an innate immune cell targeting platform to treat inflammatory diseases.
This event was held as part of our series Amplified: Race and Reality in STEM on February 22, 2021. Amplified: Race and Reality in STEM aims to give a national platform to speakers to have candid conversations around race and diversity in the STEM fields. Launched in 2020 as part of Gladstone’s commitment to diversity, equity, and inclusion, this series is hosted in partnership with Georgia Tech, the Molecular Engineering & Sciences Institute at University of Washington, and The University of Texas at Austin. We hope these discussions spark change throughout the sciences.
In Somalia, poverty is forcing women into sexual exploitation as men from the country who've emigrated to the west return to take advantage of them.

Many of the women are refugees who are lured by the offer of a better life abroad. They often go through a fake wedding ceremony. The women are later abandoned as the men return to their families in the West. It's a practice known as vacation marriage. Jamal Osman has been to Nairobi, where he put together this exclusive report. He was assisted by Nick and Deka Hassan.
